Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a piping device suitable for use in water supply and hot water supply, for example, in a bathroom unit.

[Conventional technology]

Traditionally, bathroom units have been used mainly in mid-to-high-rise residences, and the bathroom unit is fitted into the installation space at the construction site to create a bathroom (see, for example, Japanese Patent Publication No. 8163/1983).
In such bathroom units, the piping for water supply and hot water supply is installed behind the wall, so once the bathroom unit is installed, even if water leaks from the joint of the piping, it cannot be easily repaired. . However, there is a high risk of water leakage at piping connections, and as long as joints exist, it must be considered that there is a risk of water leakage.

Therefore, recently, instead of relying on rigid metal pipes that require joints at bent points, flexible pipes such as cross-linked polyethylene pipes and copper pipes are being used in the form of long bodies that do not have joints in the middle. This flexible tube is piped through a sheath tube which is a protection tube, and water and hot water are supplied through this flexible tube.

[Problem that the invention seeks to solve]

However, even in piping using such flexible pipes, it is necessary to form a joint in the piping section from the wall of the bathroom unit to the inside of the bathroom.
There was a risk of water leaking from the joint located on the back side of the wall. Such water leaks inevitably lead to water leaks in residences, uncleanliness, and corrosion of equipment.

In the above piping system, even if water leaks from the joint located on the back side of the wall, the present invention prevents the leakage from occurring on the back side of the wall and allows the water to leak from the front side of the wall, that is, on the indoor side of the bathroom unit. The purpose is to allow water leakage to escape.

[Means for solving problems]

In the present invention, a joint protection box 7 is inserted from the indoor side of the pipe insertion hole 4 of the wall 1, the protection box 7 is opened to the indoor side, and a lid 12 is provided at the opening.
A flexible tube 6 made of a long body is inserted into the protective box 7 from the back side of the wall 1, and the end of the flexible tube 6 is inserted into the protective box 7 from the back side wall of the lid 12 inside the protective box 7. A conduit 9 is connected to the connecting tube 11 formed on the front wall surface of the lid body 12 so that the flexible tube 6 and the conduit 9 communicate with each other. This relates to a piping device in which a leakage discharge hole 14 is formed in the wall surface of the lid body 12 so as to be located substantially on the same plane as the lid body 12 .

Reference numeral 1 denotes a wall constituting the bathroom unit. The wall 1 is provided with a reinforcing plate 3 on the back side of a wall 2 on the indoor side, and a pipe insertion hole 4 is formed in the wall 1. 5 is a sheath tube, and 6 is a flexible tube, and the flexible tube 6 is inserted into the sheath tube 5. The sheath tube 5 has a bellows-like wall surface and is bendable, and is made of, for example, synthetic resin or metal. The flexible tube 6 is a tube body that has excellent flexibility and can be easily bent, such as a crosslinked polyethylene tube or a copper tube. The flexible tube 6 consists of a long body,
It does not have a joint part in the middle part,
The bent portion of the pipe can also be made without a joint by utilizing its flexibility.

7 is a joint protection box, and the pipe insertion hole 4
It is inserted from the indoor side. Reference numeral 12 denotes a lid body, and a connecting tube 11 is formed inside the protective box 7 from the back wall surface of the lid body 12, and a connecting tube 10 is formed on the front side wall surface of the lid body 12.

The end of the flexible tube 6 is inserted into the protective box 7, and a joint portion of the flexible tube 6 is formed within the protective box 7. The structure of the joint part is as follows. That is, the end of the flexible tube 6 is connected to the connecting tube 11 formed in the protective case 7 from the back wall surface of the lid 12 of the protective box 7, and the connecting tube 10 is connected to the connecting tube 10 formed on the front wall surface of the lid 12. A conduit 9 to a faucet 17 is connected to.
Since the connecting tube 10 and the connecting tube 11 are formed in communication with each other at opposite positions, the flexible tube 6 and the conduit tube 9 are communicated with each other. 8 is a joint protector.

18 is a protective cover.

[Effect]

The wall 1 constitutes a bathroom unit. A flexible pipe 6 inside the sheath pipe 5 is used for piping for supplying water and hot water to the bathroom unit 1. The sheath pipe 5 has a role of protecting the flexible pipe 6, and thereby, for example, the flexible pipe 6 is not buried directly in concrete, and the flexible pipe 6 is safely arranged through the sheath pipe 5. be able to. The protection box 7 has a joint at the end of the flexible tube 6 formed therein, and has the function of protecting the joint. If water leaks from the joint inside the protective case 7, the leakage water will be discharged from the bottom 13 of the protective case 7 to the indoor side through the drain hole 14 through the gap between the protective cover 18 and the wall 1, and the wall will Water leakage does not escape to the back side of 1.

[Effect of idea]

According to this invention, if water leaks from the joint inside the protective case 7, it can be discharged indoors through the discharge hole 14 formed on the bottom of the protective case 7, Once installed, water will not leak in areas that are difficult to repair, and even if water leaks from the joint part of the protective box 7, it will not escape to the back side of the wall 1, preventing water from leaking. This will prevent piping from becoming corroded and unclean.
